$ /sbin/hwclock --debug --show
hwclock from util-linux-ng 2.14.2
Using /dev interface to clock.
Last drift adjustment done at 1251821496 seconds after 1969
Last calibration done at 1251821496 seconds after 1969
Hardware clock is on local time
Assuming hardware clock is kept in local time.
Waiting for clock tick...
/dev/rtc does not have interrupt functions. Waiting in loop for time from
/dev/rtc to change
...got clock tick
Time read from Hardware Clock: 2009/09/01 19:12:14
Hw clock time : 2009/09/01 19:12:14 = 1251821534 seconds since 1969

Every system's reboot clock goes on 3 hours up (/etc/init.d/hwclock.sh
does???).
This happened when I compiled the kernel whith Enhanced Real Time Clock
Support.
